Has a genetic cause for obesity been found, that would make one obese even if eating a typical number of daily calories?

Genes and obesity: There are 70 different genes that predispose for obesity. Some influence where fat is stored, some influence hunger, some cause binge eating, and many influence metabolism. For our bariatric patients we are finding that they burn about 8 cal per pound. That's 1600 cal per day if they weigh 200lb. For genetically thin patients, they burn 13-14 cal per pound. That person could eat 2600 cal per day.
